Blue Gene/L Torus Interconnection Network
Overview One of the most important features of a massively parallel supercomputer is the network that connects the processors together and allows the machine to operate as a large coherent entity. In Blue Gene/L (BG/L), the primary network for point-to-point messaging is a three-dimensional (3D) torus network. The main interconnect of the massively parallel Blue Genet/L is a three-dimensional torus network with dynamic virtual cut-through routing. This paper describes both the architecture and the microarchitecture of the torus and a network performance simulator. Both simulation results and hardware measurements are presented.
